The Foundation’s Polio team engaged the University of Washington's Strategic Analysis, Research & Training (START) Center to conduct a literature review identifying gender-related factors influencing Nigerian female caretakers’ decisions to vaccinate and/ or to seek care for their young children. The review identified gender factors to inform the creation of a survey instrument designed by Investigators from the Aminu Kano Teaching Hospital in Kano, Nigeria in partnership BMGF and the Imperial College of London. The review screened over 1700 articles, resulting in 61 relevant articles included in this analysis. START analysts then conducted a rapid thematic analysis to identify key themes and considerations.
